Lead aVR is a predictor for mortality in heart failure with preserved ejection fraction.
Article in Indian heart journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNormally, lead augmented vector right (aVR) has a negative T wave polarity (TaVR) in the electrocardiography (ECG). Positive TaVR and ST segment deviation in lead aVR (STaVR) have negative effects on mortality in heart failure with reduced ejection fraction patients.
aimOur aim was to investigate the relationship between lead aVR changes and mortality in heart failure with preserved ejection fraction (HFpEF) patients.
methodsWe retrospectively examined 249 patients in 2011-2015 years (mean age 70.8±11.9 years and follow-up period 38.3±9.6 months). ECG, echocardiographic, and laboratory findings were recorded and compared in the study. Existence of positive TaVR, STaVR, and quantitative TaVR values were recorded and the absolute numerical values of TaVR and STaVR were recorded from the 12-lead surface ECG (T/STaVR ratio or vice versa).
resultsThe patients were divided into two groups: living (171) and deceased (78). Age, systolic blood pressure, left atrial diameter, QRS duration, positive TaVR frequency, STaVR, absolute value of TaVR, and ratio were significantly higher in the deceased group. Age (OR: 1.106), STaVR (OR: 2.349), TaVR (OR: 1.612), and T/STaVR ratio (OR: 5.156) were determined as independent predictors for mortality.
conclusionsST segment and T wave polarity changes in lead aVR closely associated with mortality in patients with HFpEF.
